HEATING AND VENTlLATlNG FLUE-BLOCK.

Specification of Letters' Patent.

Patented Aug. 28, 1906.

Application filed September 8, 1905. Serial No. 277,495.

To all whom it may concer-71,.-

Beit known that I, FRANK JORDAN, a citi- Zen of the United States, residing at Ashland, inthe county of Jackson and State of Oregon, have invented certain new and useful Improvements in Heating and Ventilating Flue-Blooks, of which the following is a specification.

My invention relates to heating and ventilating flue-blocks, usually constructed of concrete or other fireproof plastic material.

My invention belongs directly to that particular class of blocks which are intended to be placed in a wall one upon another, with a mortar joint between them, and each block is formed with a hollow interior. The construction results in a continuous channel, or

more than one, within the blocks, adapted for transmitting the products of combustion, or heated or cooled air artificially set in mo tion, or general ventilation.

The object of my invention is the production of a flue-block having a particular and special form and construction and provided with a sheet-metal pipe forming the walls of its hollow interior, the top and bottom of the metal pipe in each block being arranged to engage the corresponding parts of the pipes of the blocks above and below it in the same manner adopted for the connection of joints of stovepipe and as set forth hereinbelow.

The special construction and arrangement of parts constituting my invention are illustrated in the accompanying drawings, of which- Figure l represents a vertical section of a single block, showing the main interior metal lining or wall. Fig. 2 is a like sectional view of my invention, showing the outer or ventilating channels lined with metal, Fig. 3 is a top plan view of the block as constructed according to Fig. l, and Fig. 4 is a like top plan view of my invention constructed in accordance with Fig. 2. Fig. 5 'represents a vertical sectional view of a flue built with my invention and shows the interior channel used as a ue and the outer channels used as heat-conveyers for delivering air heated by the flue itself into rooms of the building that are above the source of heat. Fig. 6 shows the interior channel used to transmit air artificially heated and the outer channel adapted for Ventilating purposes.

Like letters are used to refer to like parts throughout.

Considering the drawings, the letter A designates the concrete block, formed, as a rule, although not necessarily, with a rectangular cross-section and having the corresponding hollow interior B and the separated offsets or recesses O.

In Figs. 1 and 3 the letter D designates the sheet-metal pipe that forms the interior channel E of the block. It will be noted that the corners F of the metal pipe D are em bedded in the plastic material of which the block is formed. substantially as shown into the material of the block and is thus sufficiently made a part of the block. The exterior of the pipe D forms the inner closing-wall of the recesses O, which are thus converted into channels separated from each other and lying upon the four sides of the pipe D. l

Let it be assumed that my invention is to be employed as illustrated in Fig. -that is to say, the outer recesses O are to convey and deliver air heated by the products of combustion in the main channel E into upper rooms of a house. It may be desired that two of the recess-channels shall act as one, thereby delivering heatedair to upper rooms on both sides of the flue. This arrangement I have shown in Figs. l and 3, wherein will be noted the connecting passages G, operiing the rear recess-channel O into the one at the left and enabling them to deliver their heated contents as vone channel. I have found that the presence of the recess-channels O, as shown and described, acts to prevent the heat in the flue from cracking the block, which is thus preserved indefinitely. If, however, the four recess-channels O are to be thrown into one for delivering heated air or for Ventilating a room at one side only of the fiue, then the connecting-passages G are arranged as illustrated in Figs. 2 and 4.

In Figs. 1 and 2 it will be noted that the upper edge of the pipe D projects above the block and that an offset flange d is formed on the pipe at its lower end, and in Figs. 5 and 6 it is shown that the pipes D of different blocks engage each other like stovepipe-joints, forming a continuous flue.

In Fig. 5 the letter II marks a stovepipe discharging the products of combustion directly into the main channel E, which acts, therefore, as a flue. Any number of hot-air registers J may be introduced to deliver the air heated in the recess-channel O into the upl per rooms of the house.

In Fig. 6 the air in the main channel E Each corner- F extendsl IOO may be heated by a coil of steam-pipefK and delivered into upper rooms by registers'L. In this figure'gdampers M ,and N. openlinto the recess-channels Cfor Ventilating purposes.

5 The dampers may,befarrangednear the floor and ceiling or in any desired manner.

rHaving thus described my inventienand explained the mode of its operation, what I claim islo l 1. A flue-block comprising the plastic block having `an interior channel and offsets orrecesses'irom said channel, and a sheet- ,rnetal; pipel having portions. embedded in the saidz block and thereby secured to the block,

15 the said sheet-metal pipe constituting l the wall of the interior channel of the"` block, and Iforming the inner walls closing the said recesses, substantially as described.

v2. A 'iluefblock comprising the plastic zo-'bloclr having anv interior channel and offsets oryrecesses from said channel, and a rectangular sheet-metalpipehaving corners eni- `bedded in saidblock and thereby secured to 'the' block, the said pipe constituting the wall 2 5 of the interior channel of the block, and forining the inner walls closing the saidz recesses,

substantially as described.

3. A flue-,block comprising the plastic block-having a rectangular interior .channel ners embedded in saiid block between the said recesses and thereby secured to the block, the said pipe constituting the wall of the interior channel of the block and forming the inner 3 5 walls-closing the said recesses, substantially as described.-

4. A flue-block comprising the plastic block havingdally interior channel and offsets or recesses from said channel, anda ,Sheet- 4o metal pipe having portions embedded,l in said bloclcand thereby secured to the block, the saidpipe, constituting thewall of the said linterior channel of, thebloclc, and formingthe mlelvwa'llS-Closllg-the sadrecessesftheup- 45 l per end of the pipe projecting beyondlthe block, and thelower end of theplipebeing constructed anldarrangedto engagethe upper enjd of the pipe ofthe' b lock'nextbelow whereby thepip'es of succeeding blocks may 5o be connected, substantially yas 'described YIn testimony whereof I, a'HiX iny signature 'in presence of two witnesses.
